Effect of the specific hERG blocker, E4031, on the impedance and EFP signals. A Impedance signal of 12 wells in control conditions (left) and the same 12 wells after 13 mins incubation in E4031 at the concentrations indicated (right). E4031 (300 nM, 3 mins incubation) induces EAD, shown in the inset, which can lead to potentially fatal ventricular arrhythmias. B EFP signal of 12 wells in control conditions (left) and the same 12 wells after 13 mins incubation in E4031 at the concentrations indicated (right). E4031(300 nM, 30 mins incubation) also causes arrhythmic effects in the EFP mode shown in the inset.
